Click here for the wiki - most of that information is transition to this site, but for now much if it is still at the dedicated wiki site.
you can also add your own documentation there too, using your CSC credentials (i.e. knot username/password)
We will be trying to merge all the documentation into one place as we go, but feel free to use the wiki to add your own docs. If you've had questions on how to use the clusters, it's likely other people, and your lab-mates will have too!
